Abstract： Aiming at the problem that how particles affect the outcome of the solid-liquid flow processing，a hypothesis that the friction between the particle and the processing will be a vital factor that influences both the process and the polishing quality was presented. According to the real experimental processing data，the material removal was studied when the single particle comes into contact with the processing wall，using ABAQUS software. Then the experiment was set up to polish the steel strip with solid-liquid flow. The experiment results show that the abrasion is evenly distributed and the surface roughness greatly improved which means that the solid-liquid flow is valid in polishing process. The results indicate that the combined action of horizontal cutting force and vertical pressing force will cause plastically deformation and further abrasion in real machining，improving the surface roughness to mirror finish. Meanwhile，the mechanism of solid-liquid flow precision machining without tools can be viewed directly through ABAQUS software in microscopic.
